What 35mm f1.4 to f1.8 lenses would you recommend?

Hi,

I know Sony has a SEL35F18 but it's around 500$. But I'm looking for an alternative cheaper option. I am looking for something between 35mm f1.4 to f1.8 to 50mm f1.4 to f1.8.

I am planning on using a cheap adapter (rainbowimaging), do you guys have any lenses to recommend? My budget for the lens is ~60$ to 100$.

The kind of photo I'd like to take is full body portrait with good blur. Example:

Thanks for the help!
